Tooling should modify `.uproject` to enable the plugin.

nue init should modify .uproject to enable NimForUE.

Here's a sample .uproject where NimForUE is enabled by adding a new entry under Plugins.

{
	"FileVersion": 3,
	"EngineAssociation": "5.0",
	"Category": "",
	"Description": "",
	"Modules": [
		{
			"Name": "NimForUEDemo",
			"Type": "Runtime",
			"LoadingPhase": "Default"
		}
	],
	"Plugins": [
		{
			"Name": "ModelingToolsEditorMode",
			"Enabled": true,
			"TargetAllowList": [
				"Editor"
			]
		},
		{
			"Name": "NimForUE",
			"Enabled": true
		}
	]
}

We should leave it up to an unreal plugin to do this modification.
